RUFFLING ATTACHMENT Foe sEWiNe-MACHTNES.

SPECIFICATION forming part of Letters Patent No. 292,867, dated February5,1884.

Application-filed November 13, 1883. (No model.)

movements from the needle-bar, and as the power consumed by the latterin performing its ordinary functions is generally greater th an thatrequired to drive any other part of the sewing-machine, the additionallabor required of needle-bars in operating ruffiing and simi- `larattachments results in rapid wear of needle-bars or their bearings andofthe heartcams by which they are usually operated.

The principal object of my invention is to obvia-te the objection justabove indicated by a construction enabling me to operate the rufiier baror lever directly from a cani.on the needle-operating shaft journaled inthe upper portion of the machine. My construction also permits of theutilization of the rufiier bar or lever for supporting other attachmentson the machine, and I alsoprovide a separate plate of such form as willavoid friction and wear on the teeth ofthe feed-dog.

Inthe accompanying drawings, `Figure 1 is a front view of the head of asewing-machine with the face-plate removed, showing my ruffler inoperative position. Fig. 2 is a sectional side view of the same. Fig. 3is a view from the side opposite that seen in Fig. l, showing the meansqfor attaching the ruffler to the head, the ruftler bar or lever beingrepre-` sented as out of action. Figa is a detail perspective view ofthe presser-foot and its attached guides. Fig. 5 is a detail bottom planview of the separator-plate, and Fig. 6 is a section of the same on line6- 6, Fig. 5.

A indicates a portion of the bracket-arm of a sewing machine, and B thehead carried thereby.

C is the needleoperating shaft, journaled in the horizontal portion ofthe bracket-arm, and provided at its forward end witha crank-disk, D,having a crank-pin, d, for imparting mobracket, F, which is attached tothe head B by a thumb-screw, f. The lever `E has a bent upper endpassing through an opening in the side of thel head, so that it mayengage the disk-cam D, the upper end of said lever be-A ing preferablyprovided -with an anti -friction roller, e. A spring, e', attached `tothe lower portion of the lever E, and bearing against the side of thehead B, serves to force the upper end of said lever toward itsoperating-cam, the throw ofthe lever being regulated by anadjusting-screw, c, tapped in the lever above its pivotal point. Asecondscrew, e, the purpose of which will presently appear, is tapped in thelever below its pivotal point. The lower arm of thc lever E ispreferably made in two portions halved together, as shown, the portione'L being detachably connected with the upper portion by a set screw,e5, and dowel-pin e, or in any other suitable manner. rlhe rudiing-bladeeT is attached to a horizontal extension on the lower end of the leverE, and one or more guides, es, for thefabric, ruffle-strip, or piping,may also be attached to said extension above and below therufiiing-blade. l

From the foregoing it will be apparent that the portion 'el of the leverE and its Aattached ruffling-blade and guides may be removed simply byloosening the set-screw e5. The upper arm of said lever may then bethrown out of action, away from its cam, by turning in the set-screw ela suitable distance. Then by turning the set-screw e3 against'the sideof the head B, as shown in Fig. 3, the arm or lever E will be rigidlyfixed in a proper position to be utilized as a means for supportingbinders, hemmers, corders, or other attachments having properly-shapedarms or stocks in operative position on the machine.

G is the separator-plate, serving to cover a portion ofthe feed, saidplate, as is well known, separating the ruffle strip from the fabric`which passes beneath it, so that the rufiiing- IOO blade may act onsaid strip without affecting l Having thus described my invention,Iclaim 5o said fabric. The separator-plate may be provided with an arm,g, by means of which it can be attached to the bed-plate of the machineby a set-screw; or said plate may be carried by an arm fixed to theslide which covers the shuttle-race,both of these `constructions beingwell known. As the feed-dog when in operation rises slightly above theupper surface of the bed-plate of the machine, the separator-plates ofthe usual construction occasion considerable friction on thefeed-dog,and it sometimes occurs in sewing ruiiies to bands which areguided above the rufIie-strip that the teeth of the feed-dog will comedirectly in contact with the separator-plate, which, being usuallyconstructed of hardened steel, dulls the points of said teeth. To avoidthis difficulty I have provided my separator-plate with a shallowrecess, g', into which the feed-dog can rise without coming in contactwith the under surface of said plate. vThis recess may be formed bymilling when a plate of sufficient thickness is used; but it will bepreferable to make it simply by stamping a thin steel plate into properform before hardening.

H indicates a presser-foot ofthe form which I prefer to use with myruflier. This presserfoot has a square projecting toe, h, to which areattached guides h h2. The latter is inclosed, so as to be adapted forguiding piping. These guides may be removably secured to the toe 7b by asmall setscrew,so that the presser-foot .may be used for ordinary workwithout having the guides in theway, or they may be permanently fixed tosaid toe, and the foot be replaced by a foot of the ordinaryconstruction when the guides are not to be used. will be understood thatthe guides hl maybe used as supplemental to or alternatively with theguide es on the ruflier-lever.

The operation of my rufler will be readily understood by those skilledin the art to which it relates from the foregoing description. When theshaft C is rotated, the disk-cam D will impart a vibratory motion to thelever E, and the rufHing-blade el will ruffle the properly guided stripor piece of fabric in the usual manner. i

as new and desire to secure by Letters Patentl. The combination, withthe needle-operating shaft arranged above the bed-plate of the machine,of a cam on the forward end of said shaft, within the head of themachine, a rufiler bar or lever havinga pivotal support on the saidhead, a ruffling-blade carried by said bar or lever, and a spring forforcing the .latter toward said cam,substantially as described.

`2. The combination, with the head B, shaft C, and disk-cam D, of thebracket F, screw f, ruffler bar or lever E, having a ruffling-blade atits lower end and an anti-friction roller at its upper end,regulating-screw e?, and spring e', substantially as described.

3. A rufiler bar or lever having a detachable portion carrying theruflling-blade, combined with means for rigidly holding said bar orlever in a fixed position away from its operating-cam, whereby said baror lever is adapted to serve as a support for other attachments,substantiallyas described.

4. The combination, with the head B, of the bracket F, means forsecuring said bracket to said head, the lever E, pivoted to saidbracket, and the screws e2 and e3, arranged on opposite sides of thepivotal point of said lever, substantially as described.

5. A separator-plate provided with a recess for the feed-dog, wherebythe latter will be prevented from coming in contact with the undersurface of the said plate, combined with a rufiiing-blade and means foroperating the same, substantially as described.

6. The combination, with the ruffler bar or lever and theruffling-blade, of a separatorplate provided with a recess for thefeed-dog, whereby the latter will be prevented from coming in .contactwith the under surface of the said plate, substantially as described.

In testimony whereof l affix my signature in presence of two witnesses.
